4 Claims.

This invention relates to a tool designed primarily for cleaningchimneys.

Heretofore difliculty has been experienced in cleaning out the angularcorner portions of a chimney and, in order to properly clean thesurfaces it has been necessary usually to use different tools.

An object of the present invention is to combine in a single tool acleaner designed for scraping both curved and angular surfaces, it beingpossible readily to adjust the tool for either purpose.

A further object is to provide a tool which can be detachably secured toa long handle, such as a fishing pole, and thus operated in a chimney ofconsiderable length.

A still further object is to provide a cleaner which is simple inconstruction and can be used readily.

With the foregoing and other objects in view which will appear as thedescription proceeds, the invention consists of certain novel details ofconstruction and combinations of parts hereinafter more fully describedand pointed out in the claims, it being understood that changes may bemade in the construction and arrangement of parts without departing fromthe spirit of the invention as claimed.

In the accompanying drawing the preferred form of the invention has beenshown.

In said drawing Figure 1 is a front elevation of the tool adjusted foruse in cleaning out the corner portions of an angular chimney flue.

Figure 2 is a top plan view thereof.

Figure 3 is a section on line 33, Figure 1.

Figure 4 is a side elevation.

Figure 5 is a view similar to Figure 1, showing the tool adjusted foruse in scraping the curved wall of a chimney flue.

Figure 6 is a plan view of a blank from which the blades are formed.

Referring to the figures by characters of reference, A designates ablank forming a substantially semicircular blade I from the straightside of which is extended an angular blade 2. This blank is adapted tobe folded along the line 3 and it has a central slot 4 extending intoboth blades. Furthermore located in each of the blades and adjacent tothe respective ends of the slot are separate pairs of bolt holes 5 and 6respectively.

As before stated the blank, which can be made of any durable material,such as sheet steel, is folded along the line 3 so that the two bladesThe slot 4 is of such size that when the blank is folded, one endportion of an elongated handle 1 can be seated in that end portion ofthe slot located within the uppermost blade. For example, if the angularblade is uppermost, as shown in Figures 1, 2 and 3, the end portion 1 ofthe handle will extend into that end portion of the slot 4 projectinginto the angular blade 2.

The handle is secured to the blades by placing a U-bolt 8 astride thehandle and inserting the threaded terminals thereof through the openings5 in the semicircular blade l. The threaded terminals of the bolt canalso be extended through a plate 9 which acts to clamp upon theelongated looped ends I!) of a resilient loop ll constituting aring-like gauge. This loop can be made of steel or other suitablematerial and obviously by placing nuts 12 on the ends of the U-bolt 8and tightening them, all of the parts can be held together securely.

With the parts assembled as shown in Figures 1 to 3 inclusive, the toolcan be lowered into a chimney flue and the angular blade used forscraping the flat walls of the flue and up into the corners thereof. Thegauge ring II serves to hold the blade 2 pressed yieldingly against thesurfaces of the flue and it also acts to guide the tool in the flue. Byloosening plate 9 the loop can be made larger or smaller to adapt thetool to flues of different sizes.

If the flue is not angular but is round, the handle is detached, theblade I brought uppermost, and the handle then inserted into thatportion of the slot 4 extending into the blade I. The handle is thenfastened to the blade 2 by inserting the U-bolt into the opening 6 afterit has been placed astride the handle. It is also attached to the plate9 so that the resilient loop I I will thus be extended outwardly fromthe blade 2 as shown particularly in Figure 5. Thus the tool can be usedfor scraping curved flue surfaces in the same manner as heretoforeexplained.

What is claimed is:

1. A cleaning tool for chimney flues and the like including a handle, ascraping blade, means for holding the scraping blade fixedly at an angleto one end portion of the handle, a resilient ring-like gage havingoppositely extended terminal loops, and means for holding the loopsfixedly relative to each other and the handle, each of said loops beingadjustable relative to its hold- 1ng means.

2. A cleaning tool for chimney flues and the will be positioned at rightangles to each other. like including a handle, a scraping blade having aportion extended along the handle, said blade being positioned at anangle to the handle, a resilient ring-like gage having oppositelyextended terminal loops, and means engaging said loops and a portion ofthe blade for securing the loops adjustably to the handle and attachingthe blade to said handle.

3. A cleaning tool for chimney flues and the like including a handle, ascraping blade carried thereby and extended at an angle therefrom, 10

an expansible and contractable ring-like gage, and means for adjustablyconnecting said gage to the handle and blade.
